Tire Pressure Sensor Question

[slysnake]

I just had new tires put on my '05 Copperhead and put on new sensors too. I thought I would need to program the new sensors, but as I drove the car there was no low tire warning. I thought, "Great, The computer is recognizing the new sensors." Now, after over 100 miles, I have a low tire light. Tire pressure is at 32 in all tires. Could it be that it took that long and the computer just needs to be programed to recognise the new sensors? Or is it more likely there is a faulty sensor?

[Steve-Indy]

You need a dealer to reprogram it for you...OR, come to the Indy C&C held every Sat...and I'll do it for you for free. We had a famous Chicago 06 TT there last week.

What Fester Said...

[CarolinaViper]

Jumping on the thread. Same thing happen to my 2004...Can any Dodge dealer do it. I took mine to our local dealership (who recommended after market sensors), he connected his computer device under the dash (driver's side) pulled up the sensors.... and after ten minutes related he had no idea. What can I tel him after he hooks up the computer (device) and what type of device should he be using. Thanks in advance

[slysnake]

You need a dealer to reprogram it for youThat's good news, because I would hate to risk damaging the tires.

If they put in factory dodge 433mhz sensors and all four are reading correctly, dodges are auto-relearn , usually takes about 10 miles, now if they didn't program one correctly or wrecked one during install etc then yes light will be on, i believe my viper is 30psi in driver door jam sticker drop to 30psi and give it a try hopefully works if not then take it back to dodge.

[slysnake]

If they put in factory dodge 433mhz sensors and all four are reading correctly, dodges are auto-relearn ,They are the correct OEM sensors. So your statement seems to indicate one or more falulty sensors then. damn :(

[PaulP]

With a TPMS scan tool they will find out which ones not working if that is the case most tire shops have TPMS scan tools aswell

[Steve-Indy]

slysnake, IF your sensors were Mopar part number52088990AC with athe FCC ID: MRXTG224AM02 and were marked "Made IN UK SCHRADER BRIDGEPORT" then they are the CORRECT OEM sensors for the 2003-2006 Viper. and, I think that you see that they are 433 Mhz.

Sadly, other substitutes have seen sold by at least one parts supplier as well as by some uninformed Dodge parts departments. These substitutes have even been mounted, only to find that they will NOT program to said Viper TPMS modules.

It takes a Chrysler DRB III (or Chrysler wiTECH with a working DRB III emulator) to program the correct sensors. Tire shops do not have these devices...and, NO, the Bartec devices at tire shops will not work either (at least up through 2011 models) as PROVEN when Bartec was kind enough to lend me their $2700.00 model for a trial on Gen III and IV Vipers. Sadly, said trial failed to program the sensors to the Viper modules (minimalist madules that they are).

I hope this helps.

P.S.....e-mail me your address for a pic of the correct sensor.

[slysnake]

Sensors were purchased from PartsRack and Jon assured me they were the correct ones, so I'm pretty confident they are. I am taking it to the dealership this week to see if they can tell me what's up.

[Steve-Indy]

Sounds good...and, hopefully said dealer will know how to complete this process. It takes less than 2 minutes...then YOU need to drive the Viper at least 1.2 miles.

[Redx]

Hmm, i bought the sensors from JonB, had them mounted in the new wheels. Roughly 100km on them so far, and no light so far with no programming.

Which frequency is correct? other posts, on-line stores, local dealership and local part stores say for my 2004 the frequency should be 433 Mhz not 315 Mhz.

[Steve-Indy]

YOU are correct...a more detailed search says 433 Mhz. THANKS for correcting me!!

When you get it figured out, please let me know. I am in the same situation...purchased new Pilot SS and TPMS. I still had the factory sensors (10-11 yrs old) I purchased new TPMS that were OEM replacement from CarQuest. They worked for 2 weeks (Warning Light and bell went off 4 times thought that was part of teh re-learn process) But now the low pressure (no light or bell)...checked all tire pressure they were at 30 PSI. Added 7 PSI to each tire and drove 50 miles (no change)...went back to 30 PSI still have the warning. No light or bell after the initial install of new sensors. Thanks

Steve-Indy I was hoping you were right a lot easier fix just to change the sensors for the correct frequency,

[Steve-Indy]

While I replace OEM sensors with NEW OEM sensors (cheap from Tire Rack at $30.00 each), YOU may want to try Dan's (Viper Specialty) recommendation and go with his sensors which he sets up to emulate your originals (hence his post above)...noting that he states that his last longer than OEM sensors. I do not doubt what Dan says.

The main problem with our cars (03-06 and 08-10) is a dumb module, in my opinion.

[CarolinaViper]

Found the following in a service manual for the TPMS, which I'm going to take to my local Dodge Dealer. Since I replaced all 4 sensors, I think it lost all commutation between the sensors and TPM module. May with the following information the local dealership can follow the steps and relearn my sensors.

Program Mode

The Program Mode enables the TPM module to
record each wheel transmitter ID in the following
order (LF, RF, RR, and LR) in memory. The
module must learn each of the four tire pressure
transmitters’ identifications (ID.) This transmitter
ID ‘‘learning’’ is used so that if the TPM module at
this frequency is receiving any other signals, it
won’t be misinterpreted. Programming is initially
done at the assembly plant. If a TPM module fails
or one or more tire pressure transmitter(s) fails,
after replacement of the faulty component, the TPM
module must be reprogrammed to learn the transmitter
ID. The DRBIIIt places the module in Program
Mode. It is possible to reprogram only one tire
pressure sensor/transmitter. To program a sensor/
transmitter place a magnet (special tool 8192) or
transponder tool over the end of the LF wheel valve
stem for six seconds. The magnet will energize and
close a reed switch. The transponder tool will excite
the transponder coil.With the reed switch closed, or
the transponder coil energized the transmitter will
transmit the identification (ID) and tire pressure to
the module. After the module has learned that
particular tire pressure sensor/transmitter ID, the
magnet should be moved to each of the other wheels
as directed by the DRBIIIt. Hold the magnet/
transponder tool at each wheel for six seconds
before moving onto the next wheel. Exit the Program
Mode. The module will store the locations of
each transmitter ID. Using the DRBIIIt, verify that
the module programming is complete by looking at
the tire pressure sensor/transmitter ID’s and pressure
values.

but as I drove the car there was no low tire warning. I thought, "Great, The computer is recognizing the new sensors." Now, after over 100 miles, I have a low tire light. So I'm thinkng it's a bad sensor. These are new PSS tires and I've heard that they get damaged easily when they are dismounted. That's my main concern.


Thanks for that info CarolinaViper. I'll be sure to take it with me to the dealership.

[slysnake]

Finally got the car into the shop. The tech says all the sensors in the tires seem to be functioning normally but the module doesn't read them and still had the old sensor codes stored. He wasn't able to get the DRBIII to reprogram it but he was able to clear the old codes and thought it might relearn the new codes on it's own. I drove the 40 miles home from the shop but the low tire light was still on. The tech put in a call to someone at Chrysler and they seem to think it's a faulty module now. Does that seem reasonable to anybody? Never had this problem until this tire change so, to me, that's weird that the module would suddenly go bad like that just after new sensors were put in. So it's about $150 for the module and take apart the dash to put it in so who knows how much labor cost. :(

9/10 says the dealer has no idea what they are doing. They either do not know how, or cannot access the sensors/don't have the tool for sensor activation. The sensors need to be activated by a magnetic "doughnut", and they need to be located in an OEM-like position, or you cant get to them. If the module still had your old codes, it is working just fine. I have only seen ONE bad module, and it was flat out dead. Unfortunately, by clearing the old codes, they also just tossed a monkey wrench into emulating the old sensors and just swapping them.

[slysnake]

If the module still had your old codes, it is working just fine.That's what I suspected. I have an appointment now at Roanoke for Friday. I think they will know how to do it right.

[CarolinaViper]

Let me know how it goes. I wait to take mine in afterwards. Thanks in advance

[Steve-Indy]

CarolinaViper...call me

...-...-....

[bluesrt]

I think you have the wrong vendor :)

oops... hey dan lets get some cf gen v mud guards going! :t89039:

[CarolinaViper]

CarolinaViper...call me

...-...-....

Can't read the phone number

[slysnake]

Finale to the story. a few minutes at Roanoke and now everything is fine. :) Just needed a tech that knew how to do it.

[redrichard]

Good to here.

[Steve-Indy]

And now you know why I make so many "house calls" around Indy to program these sensors. It's simple with the right tools and a little knowledge!!

[Vipes]

You need a dealer to reprogram it for you...OR, come to the Indy C&C held every Sat...and I'll do it for you for free. We had a famous Chicago 06 TT there last week.

Hey Steve. I finally came out to a C&C today for the first time. I went looking for you but everybody said you weren't there. I was going to ask you about the sensors, I have the same problem. It was nice finally meeting other viper owners, great group of guys! Maybe next time I'll catch you.

Troy

[Steve-Indy]

Sorry...had another obligation.

Call me.

[Steve-Indy]

LunchBox...you coming to C&C tomorrow?

[Vipes]

LunchBox...you coming to C&C tomorrow?

Hey Steve, no I'm heading out of town in the morning. I might try and go next weekend. ttyl

[Steve-Indy]

Understood...call me if/when you want to try to program the tire pressure sensors.
